Warmer spring temperatures and a growing body of literature on the importance timely planting have resulted in many growers Michigan other northern U.S. states soybean [Glycine max (L.) Merr.]. However, there is limited research informing how management practices should be adjusted based date (PD). Field experiments were conducted at two locations using split-plot design during 2018 2019 season...

BACKGROUND Inefficient experimental designs are common in animal-based biomedical research, wasting resources and potentially leading to unreplicable results. Here we illustrate the intrinsic statistical power of split-plot designs, wherein three or more sub-units (e.g. individual subjects) differing in a variable of interest (e.g. genotype) share an experimental unit (e.g. a cage or litter) to...
